We are timeshare owners at an AI resort in the Riviera Maya. We negotiated several corporate weeks (which are free weeks) when we bought the timeshare a year ago thinking we might want to get married there. Even if we decided on another place for the wedding we would have the corporate weeks for ourselves to use in the future. We ended up deciding to get married there. So now we can let our close friends and family use our corporate weeks to stay the week for free, they just need to pay their mandatory per person AI fee of $99/day. Some resorts have an AI option, but this resort doesn't...it is mandatory. However, I've been there before and can assure all my guests that the food is delicious. There are 7 or 8 restaurants to choose from. Not to mention the bars have great variety, not just wells like many of the other AI resorts. So for us and our guests, the AI is way more cost effective.
